Choc Chip, Sultana & Oat Slice (lunchbox recipe)

This Choc Chip, Sultana & Oat Slice slice is the perfect lunchbox filler! It’s so easy, takes only 10 minutes to prepare and is absolutely delicious. 

I’m one of those people who loves to have a piece of slice with my cuppa. Sometimes I like my sweet treats to be chocolatey (hehe, ok a LOT of the time), other times I prefer something fruity, and I do, of course, love an oaty or coconuty treat too. Well this slice ticks all those boxes because it has a little bit of chocolate, a little bit of fruit, a little bit of oaty-ness and a little bit of coconut. So now there’s no more having to choose!!

This is one of those slices that is so quick and easy to make. You simply pop all of the dry ingredients into a bowl and give them a good stir. Add the cooled melted butter and the whisked egg and mix together. That’s it. Well nearly! You do still have to actually cook it too… but that’s just as easy!

I love this slice because there’s no fancy-pants ingredients in it. Pretty much everything will be in your cupboard and fridge. It’s also incredibly yummy (which is the most important thing).

Choc Chip, Sultana & Oat Slice My Choc Chip, Sultana & Oat Slice would be the perfect match for your morning cuppa or as a lunchbox snack.

This slice really is so versatile. Since I made this a couple of weeks ago, I have also made a white chocolate and apricot version and my next experiment is going to be with cranberries and pistachios. It’s the perfect recipe base to mix and match with your favourite ingredients.

So my advice is to go and whip up a tray of this slice, make a cuppa and then sit outside and enjoy the sunshine!

    I made this but substituted the milk chocolate chips and sultanas with cranberries and whit chocolate….yummy 🙂

    1. Bake Play Smile says:

      Yay! Good for you Emily! 🙂 It’s so versatile, isn’t it! I’ve also made a version with apricots and white chocolate which is amazing – that one will be on the blog in the coming weeks. xx

  2. I love chocolates as my cuppa partner, too :). I don’t have a particular favourite ‘coz I get to discover several potential partners, including this one!

      Ooooh yes nothing like discovering new choccies! xx

  3. Hope says:

    Oh yummy. I’m just like you, I always need something little to go with my tea. Doesn’t have to be a biscuit but something sweet and slice-like. Bookmarking this one! Oh and love the food photography, looks really good. xx

    1. Bake Play Smile says:

      Thank you so much – I really appreciate that. I’m very much a beginner, but it’s something I’m working on.

  4. I’d love to try this with dates! Yum

    1. Bake Play Smile says:

      Perfect! It’s so versatile! 🙂

    2. Tahnee says:

      I didn’t have sultanas so I used chopped dates and diced apple and it’s still delicious!

      1. Lucy Mathieson says:

        Yay!!! That’s great to hear!

  5. Don’t hate me because I don’t like sultanas in my food but I don’t – I’d just replace with white chocolate!

    1. Bake Play Smile says:

      Hehe nothing wrong with milk chocolate and white chocolate Em! xx

  6. Chocolate and coconut are wonderful but I’m afraid I am one of those folk who picks the sultanas out of the oats or muesli before eating. Why ruin it? 😉 The only thing I’d add is a dash of some sort of nut. Yum. #teamIBOT

    1. Bake Play Smile says:

      Haha oh really!! Mm nuts would be good too! 🙂

  7. I think I have all of these ingredients in the cupboard. I’m tempted to make it for the kids tomorrow x

    1. Bake Play Smile says:

      Perfect! Hope you love it! xx

  8. Trish says:

    My boys (and the big ones) will love this.

  9. Trish says:

    I made it , this morning – it’s delicious but mine was very crumbly – how did you get it so perfect looking ?

    1. Bake Play Smile says:

      Hi Trish,
      The most important thing is to not overmeasure the flour – that’s my biggest tip! 🙂

    2. Bake Play Smile says:

      Oh actually one more thing – you need to make sure the slice was completely cooled before cutting it (otherwise it will crumble!). A few hours is good – but overnight is even better!! 🙂 That’s only if you want your slices to look neat – otherwise go for it and cut a bit earlier! 🙂

  10. Can I please win the lottery and hire you as my live in baker, and never get fat because I would also have my live in personal trainer. Duh! i’m bookmarking this recipe!

    1. Bake Play Smile says:

      Hahaha absolutely!!! That would be fun!! xx

  11. I have a confession to make. I absolutely love those choc chip oat slices you buy in the supermarket- the individually wrapped ones. They have about a zillion grams of fat (32g actually) and are probably full of fake ingredients but I try not to look. These look just like them but without the fake! Can’t wait to try them.

    1. Bake Play Smile says:

      Hahaha that’s ok! Go for it 🙂

  12. Not sure if you got my first comment…2nd try. Fantabulous combo of ingredients, Lucy. I’m looking forward to an apricot white chocolate for the first batch =)

    1. Bake Play Smile says:

      Thanks! Yes the Apricot & White Choc version is absolutely lovely! Can’t wait to share it with you. xx

  13. Jo says:

    Another winner here Lucy. I actually prefer slices to cakes and this one was enjoyed by all:)

    1. Bake Play Smile says:

      Oh yay! I’m so glad to hear it!

  14. Anna says:

    Hi, I made this but used sultanas, cranberries, sunflower and pumpkin seeds. I also used a flax egg. Just wondering if it would work if I substituted rice malt syrup for the brown sugar?

    1. Bake Play Smile says:

      You could definitely try!! You just might find that you need to add a bit more liquid. xx

  15. Olivia says:

    Made this last night and after a night in the fridge it’s really nice! But – I used only 1/3 cup of each of these; coconut, sugar, sultanas & chocolate chips and I’m SO glad I did because all of those ingredients are sweet and ANY more sweetness would have been WAY too much for me. I think I’d even be happy with 1/4 cup of brown sugar.

    1. Bake Play Smile says:

      That’s awesome!! That’s great to know that you were able to educe the sugar too xx

  16. Katie says:

    These look great! How long do they last in an airtight container? Can they be frozen?

    1. Lucy Mathieson says:

      Hi Katie, yes they can be frozen or they’ll last about 5 days in an airtight container. xx
